Buyer’s Guide

When buying a cheap generator under $500, it is essential to focus on its features to get the best possible machine according to your needs. Here in this buying guide, we are going to highlight those features.

Output and Power Needs

Once you have decided about buying an inverter or a conventional generator, the next step is to select the power output. We suggest that you don’t make any estimates while doing this. The best way to calculate your power needs is to make a list of all the appliances you want to power during a generator and then select the most appropriate one. Consider the example below.

Appliances Starting Wattage Running Wattage
Refrigerator 1400 300
1/2 HP Furnace 2350 875
TV 400 400
Lights 300 300
AC 1800 1200
Total 6250 3075

In the above example, we require 6250 watts to start all the appliances at one time and 3075 to keep them running together. You need a generator that can provide you with a running wattage of 3500 watts to power this setup. A mid-range generator is perfect for a small family’s residential use, small RV, and outdoor purposes. You can make a list of all the appliances and then find out the total required wattage.

Single Fuel vs. Dual Fuel

The next thing to consider is the type of fuel. A dual fuel generator is always better than a single fuel generator because it gives you the freedom of running your generator on two fuels. You may not be able to find gas due to a disaster or bad weather. In such situations, stored propane will come in handy. Propane’s shelf life is more than gas. Stored cylinders of propane can last for 8-10 years without any issues. Propane is also cheaper than gasoline. You will be surprised to know that a small dual fuel generator (under 5000 watts) gives a better runtime on propane than gas. Propane is also cleaner to burn than gasoline, and its exhaust is less harmful to the environment.

Inverter vs. Conventional Generator

Inverter and conventional generators are different in many ways.

Inverter machines are compact and lighter in weight. They produce pure sine waves so that users can power their smartphones, tablets, and laptops without worrying about power surges. Also, their parallel capability allows them to double the output power. Moreover, the eco-mode automatically adjusts the engine’s speed according to the applied load. But they produce less energy and have smaller fuel tanks.

On the other side, most of the conventional power machines are heavier but highly portable. They feature big fuel tanks that offer extended runtime. Also, they are capable of producing higher power output. But, they are louder than inverters, and not all their models are safe for powering sensitive electronics.

Power Output

Before buying a generator, it is necessary to find out how many and what type of appliances and tools you are going to power. If you need a generator to power your campsites or tailgates, then 2000 running watts are enough. Or if you want to buy a conventional generator to power big appliances and tools, 4000 running watts will be enough.


Runtime not only depends on the fuel tank size. The generator type, the load applied, and the type of fuel also causes the runtime to vary.

If you are buying a conventional generator, make sure its fuel tank is more significant in size. It will help you to get a reasonable runtime. Also, try to buy a dual fuel generator because propane gives more runtime than gasoline.

On the other hand, inverter generators offer excellent runtime despite having smaller fuel tanks. They do so because of the eco-mode that adjusts the engine’s speed according to the power load.

Control Panel

It is also necessary to focus on the control panel of your generator. Make sure the power outlets available will help you to power all your required appliances and tools.

Noise Level

Always avoid buying louder generators. Inverter generators make a less operational sound than big size conventional generators. But still, many traditional machines come with a noise-reducing muffler that keeps the sound rating on the lower side.


Overload sensor and low-oil shutoff are the most common safety features. Your selected generator must have both of these for the safety of your generator. An automatic voltage regulator provides stable voltage, and a spark arrestor keeps your generator and its surroundings safe from dangerous sparks.

Paralleling Capabilities

Generators under $500 are likely to have a small power output. Hence, it is better to look for a generator that comes with a paralleling feature. It allows you to connect two generators and enhance the power output for running heavy appliances. Same model inverters can be made parallel without any issues. For conventional generators, you will need to install a paralleling kit. Please note that the results may not be satisfied with a paralleling kit, and you may experience fluctuations.

Power Outlets

You will rarely be connecting a small generator to your home. Most of the time, you will power the appliances directly with the generator. Therefore, it is best to buy a generator that offers maximum power outlets. Look for a generator that can accommodate all your appliances directly.


A small generator must offer excellent portability. Inverters are lightweight compared to classical generators. Regardless of the type of generator, you must look for high-quality wheels, carry handles, and a lifting hook to make your generator highly portable.

Starting Mechanism

It is best to have two starting mechanisms in your machine. You may not always want to pull the starting rope every time the power goes out, or you are outdoors. Hence, it is better to have an electric start option as well. Electric start generators are a bit costly as compared to recoil starting models. Remote start generators are expensive and don’t come under the range of $500.

Warranty and Certifications

Look for a generator that offers maximum warranty and comes with certifications from EPA. Such add-ons increase the value of your money and give you peace of mind. A warranty helps you get your generator fixed in case of any defaults during the warranty period. Make sure you read all the terms and conditions associated with the warranty.


The price is already under $500 for all the generators. Hence, there is no point pondering over price and features. All the generators in our list are the best in this range.


Are generators under $500 reliable?

Yes, there is no doubt about that. Various famous companies make budget-friendly generators. These manufacturers include ChampionWENDuroMaxWestinghousePulsar, and others. All of these companies offer not only conventional units but also inverter generators that are reliable and durable. But you cannot get a generator under $500 with higher power output. Also, its regular usage can reduce its lifespan.

Which type of generator is best to power sensitive electronics?

An inverter generator is a better choice to power sensitive electronics because it produces clean and stable power. Many conventional generators feature less than 5% THD rating and an AVR (automatic voltage regulation) system to provide durable power. But in the case of inverter generators, every unit produces a pure sine wave. So, if you need a generator that can power your delicate electronics, buy an inverter generator.

How much power do you need to run your home appliances?

You can get a 4000-watt generator under $500 to power two big and one medium-sized home appliances. The refrigerator needs continuous running during a power outage that consumes 700 watts of power. You can also power a medium-sized central air conditioner to keep your house cool during hot summer days. It consumes 1500 watts of power. Water is also a basic necessity, so you can also power a water pump that utilizes 600 watts. Moreover, you can run some small tools in your garage or a washing machine.

Generators under $500 are compact and small in size. How can I avoid generator theft?

It would be best if you always store your generator in a safe place. To keep them safe from being stolen while running, use generator locks and cables, and metal brackets for inverters.

What are the maintenance needs of a small generator?

The maintenance needs of a small generator are the same as compared to a large generator. Either you are buying a generator under $500 or $5000, the maintenance schedule is the same. You will need to change the oil timely, spark plugs, oil, air filters, battery inspection, store the generator properly, and emoting the fuel tank and carburetor before storing it.

What’s the safe distance of running a generator?

The EPA recommends that you run your generator at least 15 feet away from your living space or sitting area.

What are the benefits of buying a generator under $500?

First of all, you can save a lot of money upfront. Secondly, maintenance and repairs for a smaller generator are easy and less costly than larger units. Storing, handling, and traveling with a small generator is also convenient as compared to large generators.

What are the limitations of a generator under $500?

The only limitation is their low power output. Cheap generators can’t produce large amounts of power. They are not ideal for every day or commercial use.


Finding a generator under $500 has now been made easy for you. We have listed the best 7 generators for you to buy. Select the one according to your needs and the information given in the buying guide. Don’t worry; all the units are high-quality, reliable, and durable.
